If car owners aren't paying for the power, then who is?
And either way, what does it cost to wire up all the parking spaces?
Paid parking lots solved that problem eons ago.

I wonder how people ever managed to electrify street lamps, any exterior powered things, even the per-stall electric parking meters I've encountered.
All I'm saying is, the costs of these sorts of demand management measures for renewables should not be overlooked in comparisons with the cost of nuclear, which doesn't need them.
True, you'll need a heavier wire. And the cost of installing wire far exceeds the cost of the wire. When my house was wired up, the cost of the installation was 40 times the cost of the reels of wire.
If every parking space had a 7 kW connection (230 V, 30 A single phase) almost all cars could be fully charged while their owners were at work. In fact even an ordinary 3 kW connection would be enough for most people; even my 2015 Tesla Model S adds more than 12 km per hour at 3 kW.
